Event ‘consistent with an explosion’ near last known location of missing sub – Argentine navy

An unusual sound detected around the time that an Argentine navy submarine sent its last signal before going missing last week was “consistent with an explosion,” according to a navy spokesperson. It occurred near the last known location of a missing submarine carrying 44 people.

It comes as a dozen countries are conducting a search and rescue mission for the ARA San Juan, which disappeared on November 15. It was believed that that those on board could have still been alive, but running out of oxygen.

Search teams have been covering an area of some 185,000 square miles (480,000 square kilometers), which is roughly the size of Spain.
